One major exception are M4A encoded audio streams, received from a professional DAB+ receiver. Because of the tables included in the stream, the used memory of the process increases without any limits until the process crashes. I know, it's not a bug, it's a feature, but this feature kills my recorder every few days. My plan is to add an option to the decoder in mov.c to ignore all tables included in the stream. I would like to send my changes as a patch to this mailing list. Would you incorporate such a patch into the source tree? Of course, the default behavior of the decoder should not change at all and I already read the description of the acceptance process for patches.

Hi Jorg,

	Can you leave the dash link here, I want check about that, and try to fix it.


Thanks
